A because if he was a leader he’d take the kick himself and they’re are not all working to kick the ball so it’s not teamwork and it’s not sportsmanship because he isn’t stopping a fight or fixing something between two teams

A 5kg box is being pulled for a force of 20 n and is sliding with an acceleration of 2 m/s. Find the coefficient of friction
RUDIKE [14]

Answer:

Coefficient of friction = 0.5

Explanation:

Given:

Mass of box = 5 kg

Force applied = 20 N

Acceleration = 2 m/s²

Find:

Coefficient of friction

Computation:

Friction force = Mass x Acceleration.

Friction force =  5 x 2

Friction force = 10 N

Coefficient of friction = Friction force / Force applied

Coefficient of friction = 10 / 20

Coefficient of friction = 0.5

Increasing the # of pulleys increases the _______ but decreases the amount of ______ applied
Maksim231197 [3]

Distance, Force

<u>Explanation:</u>

1)  Increasing the load will add to the friction on the bearings of the pulleys, thus reducing the efficiency of the system.  The ideal mechanical advantage won't change since the ideal mechanical advantage ignores friction.

2)  Increasing the number of pulleys will increase the ideal mechanical advantage, but because of friction it will decrease the efficiency.  The more pulleys that are turning, the more friction there is, and the less efficient the system will be.

3)  Work = force x distance, and what machines do is alter the amount of force you can apply while at the same time reducing the distance moved by the same factor.  For instance, a jack multiplies the force you apply by a factor of 100, when you push down on the handle of the jack 100 cm, the car will only go up 1 cm.  So the force x distance is the same 100 x force x 1/100 x distance.

A 450-N rightward force is used to drag a large box across the floor with a constant velocity of 1.2 m/s. The coefficient of fri
Nikolay [14]

Answer:

the mass of the box is 51.98 kg.

Explanation:

Given;

applied horizontal force, F = 450 N

coefficient of friction, μ = 0.795

constant velocity, v = 1.2 m/s

At constant velocity, the acceleration of the object is zero and the net force will be zero.

F_{Net} = F - F_k\\\\0 = F - F_k\\\\F_k = F\\\\\mu \ N = F\\\\\mu (mg) = F\\\\m = \frac{F}{\mu  g} \\\\m = \frac{405}{0.795 \ \times \ 9.8} \\\\m = 51.98 \ kg

Therefore, the mass of the box is 51.98 kg.
